When attempting to do the restore to a clean engine install before engine setup is run as per the documentation, the restore ends with an error about restoring the history.

If I continue and run engine-setup, then it fails with the following.
It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode
Perhaps you ran engine-setup more than once? The above error message should not happen on the first (successful) run immediately after restore.

When restoring a self hosted-engine from a backup, the documentation at
https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restorin...
Shows creating a new host server and then doing the hosted-engine —deploy and manually installing the ovirt-engine instead of using the ovirt-engine-appliance. If the hosted-engine deployment that was backed up and is being restored, was created using the appliance, should I still follow this documentation and manually install the engine, run the restore, then do the engine-setup? Or should I use the ovirt-engine-appliance and just run the restore before the engine-setup?
There is no inherent difference between using the appliance and not using it. Recent versions, though, only allow using the appliance - so now you really have no option. You do have to make sure you do not ask 'hosted-engine --deploy' to automatically run engine-setup - you have to manually login, restore, then run engine-setup. Best,
Gary
